Was it the throngs of young, screaming 'Twilight' fans that caused actor Robert Pattinson's hair to stand on end?

The star of the hot vampire flick had an encounter with the forces of nature on Wednedsay night as he left GMTV studios in central London.

Robert's locks looked wild and shaggy as the strong winter winds tousled his hair!

Don't miss Robert playing dreamy vampire Edward Cullen in 'Twilight' now in theaters.
